Many people are not even aware of this feature, because this
"window mode" has been quite broken for a while in GTK+ 2.x,
however in my opinion it is very useful.

GTK+ used to handle that by translating the coordinates, I
don't know this works with Wayland, does Wayland have to
care about that at all? Does it have XInput-like semantics
of master/slave/floating? Or is all of that handled in
the GDK backend?
